[0020] In the description of the present application, the description with reference to the terms "one embodiment", "an embodiment", "illustrative embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0021] In the prior art, the general label paper shortage printing error logic often requires that the paper shortage error is triggered only when the end of the paper passes under the print head. Based on this label paper shortage printing error, during the label manufacturing process, a complete label often cannot be printed at the end of the paper. When printing the last label, part of the label may be printed above the tape between the end of the paper and the paper roll core, thereby causing the last printed label to be unable to be used normally, reducing the integrity of the label printed by the printer.

[0022] Based on this, an embodiment of the present application provides a printer control method, a printer and a storage medium. By setting a stop printing target value when the printer stops printing, when the print medium sensor cannot detect the print medium, the current number of unprinted labels is obtained, and the current number of unprinted labels is compared with the stop printing target value to obtain a comparison result; when the comparison result is that the current number of unprinted labels is equal to the stop printing target value, the printer is controlled to stop printing, and then through the comparison result between the current number of unprinted labels and the stop printing target value, the printer can accurately determine the time to stop printing when the print medium cannot be detected, thereby avoiding the print content from being printed on non-printing media, thereby improving the printing effect of the printer.

[0023] A control method for a printer, a printer, and a storage medium provided in an embodiment of the present application are specifically described through the following embodiments. First, a control method for a printer in an embodiment of the present application is described.

[0024] It should be noted that the control method of the printer is applied to a printer, the printer includes a print processor and a print medium sensor, the print medium sensor is used to detect the position of the print medium, and the print processor is respectively connected to the print head and the print medium sensor for communication.

[0025] Reference Figure 1 As shown, Figure 1 It is a flowchart of a printer control method provided by an embodiment of the present application. The printer control method may include but is not limited to steps S110 to S120.

[0026] Step S110: Setting a stop printing target value when the printer stops printing.

[0027] The stop printing target value is a value of Z print media to be printed that are reserved by the printer when the printer stops printing.

[0028] Step S120: when the print medium sensor cannot detect the print medium, the number of currently unprinted labels is obtained.

[0029] The current number of unprinted labels is the value of the distance between the print head and the print medium sensor that actually needs to print X print media.

[0030] Specifically, the print processor first controls the rotation of the printer's print roller to take the paper containing the print medium out of the paper roll core and accurately transport it to the printer's print path. After the paper reaches the printable position of the print head, the print processor controls the print head to print content on the print medium of the paper according to a preset print task; then, the print medium sensor installed on the printer's paper feed path continuously detects whether there is print medium on the printer's print path. When the print medium sensor continues to fail to detect print medium on the printer's print path, the print processor obtains the current number X of unprinted labels.

[0031] Step S130: Compare the current number of unprinted labels with the stop printing target value to obtain a comparison result.

[0032] Specifically, the current number of unprinted labels X is compared with the stop printing target value Z to obtain a comparison result.

[0033] Step S140: When the comparison result is that the current number of unprinted labels is equal to the stop printing target value, the printer is controlled to stop printing.

[0034] When the comparison result is that the current number of unprinted labels is equal to the stop printing target value (ie X=Z), the printer is controlled to stop printing.

[0035] Further, refer to Figure 2 As shown, Figure 2 This is an embodiment of the present application. Figure 1 In the flowchart of step S120, the control method of the printer may include but is not limited to steps S210 to S230.

[0036] Step S210: Obtain the printing distance value between the print head of the printer and the print medium sensor, and the printing length value required for the print head to complete a printing task on the print medium.

[0037] In some possible implementation examples, the print processor obtains a printing distance value of 105 mm from the print head of the printer to the print medium sensor of the printer, and a printing length value of 25 mm required for the printer to complete a printing task on a print medium.

[0038] In some possible implementation examples, the print processor obtains a printing distance value of 105 mm from the print head of the printer to the print medium sensor of the printer, and a printing length value of 35 mm required for the printer to complete a printing task on a print medium.

[0039] In some possible implementation examples, the print processor obtains a printing distance value of 105 mm from the print head of the printer to the print medium sensor of the printer, and a printing length value of 110 mm required for the printer to complete a printing task on a print medium.

[0040] It should be noted that the printer needs to calibrate the length of the print medium before each printing to obtain the corresponding print medium length and medium gap length, wherein the print medium length is the length of one print medium, and the medium gap length is the gap length between each print medium, and then the print medium length and the medium gap length are summed to obtain the print length value. For example: the print medium is calibrated in length to obtain the corresponding print medium length of 15 mm and the medium gap length of 5 mm, and then the print medium length of 15 mm and the medium gap length of 5 mm are summed to obtain a print length value of 20 mm. Therefore, the print length value required to complete a printing task is the distance value of the current print medium length plus the medium gap length. Preferably, if the current printing medium is a label, the print length value required to complete a printing task on a label is the distance value of the current label length plus the gap value between labels.

[0041] Step S220: According to the ratio between the printing distance value and the printing length value, confirm the theoretical value of the task to be printed that can fully complete the printing task between the print head and the print medium sensor, and set the stop printing target value according to the theoretical value of the task to be printed.

[0042] The theoretical value of the task to be printed is the value of the distance between the print head and the print medium sensor that can completely print Y pieces of media.

[0043] In some possible implementation examples, the ratio between the printing distance value of 105mm and the printing length value of 25mm confirms that the theoretical value of the task to be printed Y=4 between the print head and the print medium sensor can fully complete the printing task, and sets the stop printing target value based on the theoretical value of the task to be printed Y=4.

[0044] In some possible implementation examples, the ratio between the printing distance value of 105mm and the printing length value of 110mm confirms that the theoretical value of the task to be printed Y=0 between the print head and the print medium sensor can fully complete the printing task, and sets the stop printing target value based on the theoretical value of the task to be printed Y=0.

[0045] Further, refer to Figure 3 As shown, Figure 3 This is an embodiment of the present application. Figure 2 In the flowchart of step S220, the control method of the printer may include but is not limited to steps S310 to S320.

[0046] Step S310: When the ratio of the printing distance value to the printing length value is greater than 0 and less than 1, it is confirmed that the theoretical value of the task to be printed is 0.

[0047] In some possible implementation examples, the printing distance value is 105 mm and the printing length value is 110 mm, then the ratio of the printing distance value to the printing length value is 0.9545, and the ratio 0.9545 is greater than 0 and less than 1, confirming that the theoretical value of the task to be printed Y=0.

[0048] Step S320: according to the theoretical value of the task to be printed, the stop printing target value is set to 0.

[0049] Specifically, according to the theoretical value of the task to be printed being Y=0, the target value for stopping printing is set to Z=0.

[0050] It should be noted that when the stop printing target value is set to 0, the menu option parameter value currently displayed by the printer can also be changed to a parameter value of "automatic" or "Auto", wherein the parameter value of "automatic" or "Auto" indicates that the current printer is in automatic printing mode.

[0051] Reference Figure 4 As shown, Figure 4 Another embodiment of the present application provides Figure 2 In the flowchart of step S220, the control method of the printer may include but is not limited to steps S410 to S420.

[0052] Step S410: When the ratio of the printing distance value to the printing length value is equal to or greater than 1, confirm that the theoretical value of the task to be printed is a positive integer obtained by rounding off the decimal point of the ratio.

[0053] In some possible implementation examples, the printing distance value is 105 mm and the printing length value is 25 mm, then the ratio of the printing distance value to the printing length value is 4.2, and the ratio 4.2 is greater than 1, then it is confirmed that the theoretical value of the task to be printed is the positive integer 4 obtained by rounding down the decimal point of the ratio 4.2 (ie, Y=4).

[0054] Step S420: according to the theoretical value of the task to be printed, the stop printing target value is set to a value equal to the theoretical value of the task to be printed.

[0055] Specifically, according to the theoretical value of the task to be printed being Y=4, the stop printing target value is set to a value equal to the theoretical value of the task to be printed (ie, Z=4).

[0056] Reference Figure 5 As shown, Figure 5 Another embodiment of the present application provides Figure 2In the flowchart of step S220, the control method of the printer may include but is not limited to steps S510 to S520.

[0057] Step S510: When the ratio of the printing distance value to the printing length value is greater than 1, confirm that the theoretical value of the task to be printed is a positive integer obtained by rounding off the decimal point of the ratio.

[0058] In some possible implementation examples, the printing distance value is 105mm and the printing length value is 35mm, then the ratio of the printing distance value to the printing length value is 3, and the ratio 3 is greater than 1, then it is confirmed that the theoretical value of the task to be printed is the positive integer 3 obtained by rounding off the decimal point of the ratio 3 (ie, Y=3).

[0059] Step S520: according to the theoretical value of the task to be printed, the stop printing target value is set to any positive integer between 1 and the theoretical value of the task to be printed.

[0060] In some possible implementation examples, according to the theoretical value of the task to be printed Y=3, the stop printing target value is set to any positive integer between 1 and the theoretical value of the task to be printed Y=3 (for example, the stop printing target value is set to X=3).

[0061] In some possible implementation examples, according to the theoretical value of the task to be printed Y=3, the stop printing target value is set to any positive integer between 1 and the theoretical value of the task to be printed Y=3 (for example, the stop printing target value is set to X=2).

[0062] In some possible implementation examples, according to the theoretical value of the task to be printed Y=3, the stop printing target value is set to any positive integer between 1 and the theoretical value of the task to be printed Y=3 (for example, the stop printing target value is set to X=1).

[0063] It should be noted that the printing mode of the printer can be divided into an automatic printing mode and a custom printing mode. When the printer is in the custom printing mode, the above step S520 is executed; when the printer is in the automatic printing mode, the above step S320 or step S420 is executed.

[0064] Further, refer to Figure 6 As shown, Figure 6 It is a flowchart of a printer control method provided by another embodiment of the present application. The printer control method may include but is not limited to steps S610 to S620.

[0065] Step S620: When the comparison result is that the current number of unprinted labels is greater than the stop printing target value, the printer is controlled to continue printing until the current number of unprinted labels is equal to the stop printing target value, and the printer is controlled to stop printing.

[0066] In some possible implementation examples, when the comparison result is that the current number of unprinted labels X=5 is greater than the stop printing target value Z=4, the printer is controlled to continue printing so that the current number of unprinted labels X decreases by one after each printing medium is printed, until the current number of unprinted labels X=4 is equal to the stop printing target value Z=4, and the printer is controlled to stop printing.

[0067] Further, refer to Figure 7 As shown, Figure 7 It is a flowchart of a printer control method provided by another embodiment of the present application. The printer control method may include but is not limited to step S710.

[0068] Step S710: When the comparison result is that the current number of unprinted labels is less than the stop printing target value, the stop printing target value is adjusted to the current number of unprinted labels, and when it is determined that the adjusted stop printing target value is equal to the current number of unprinted labels, the printer is controlled to stop printing.

[0069] In some possible implementation examples, when the comparison result is that the current number of unprinted labels X=3 is less than the stop printing target value Z=4, the stop printing target value is adjusted to the current number of unprinted labels (i.e. Z=3), and when it is determined that the adjusted stop printing target value Z=3 is equal to the current number of unprinted labels X=3, the printer is controlled to stop printing.

[0070] It should be noted that, after controlling the printer to stop printing, the printer control method may further include: controlling the printer to display information for prompting to replace the printing medium.

[0071] In a second aspect, the present application also provides a printer, referring to Figure 8 , Figure 8 A schematic diagram of a printer according to an embodiment of the present application is provided, wherein the printer 800 includes: The print medium sensor 801 is used to detect the position of the print medium; A print processor 802, the print processor 802 is in communication with the print medium sensor 801; The print processor 802 is used to set a stop printing target value when the printer stops printing; The print processor 802 is also used to obtain the current number of unprinted labels when the print medium sensor cannot detect the print medium; The print processor 802 is further used to compare the current number of unprinted labels with the stop printing target value to obtain a comparison result; The print processor 802 is further configured to control the printer to stop printing when the comparison result shows that the current number of unprinted labels is equal to the stop printing target value.

[0072] The above-mentioned printer 800 and the control method of the above-mentioned printer are based on the same inventive concept. The above-mentioned process describes the specific implementation method of the printer 800 of the embodiment of the present application. By setting the stop printing target value when the printer stops printing, when the print medium sensor cannot detect the print medium, the current number of unprinted labels is obtained, and the current number of unprinted labels is compared with the stop printing target value to obtain a comparison result; when the comparison result is that the current number of unprinted labels is equal to the stop printing target value, the printer is controlled to stop printing, and then through the comparison result between the current number of unprinted labels and the stop printing target value, the printer can accurately determine the timing to stop printing when the print medium cannot be detected, thereby avoiding the print content from being printed on non-printing media, thereby improving the printing effect of the printer.
